IMPROVEMENT IN COMPRESSION STOPS AND WASTES.

Specification forming part of Letters Patent No. 156,633, dated October6,1874; application filed June 17, 18 74.

To all whom it may concern: 7

Be it known that I, GEORGE F. B'ARD, of Norwich, in the county of NewvLondon and State of Connecticut, have invented a Compression Stop andWaste, of which the following is a specification:

The figure is a longitudinal section'of the device, in which B and C arethe two induction and eduction passages; 11 and d, the tworubber-cushioned valves a, the slotted stem f, thcoutlet for Waste; a,the spindle to operate the device.

When the upper valve is closed, (and it always is when the lower one isopen,) the water cannot get into the upper chamber. It therefore cannotrun out of the waste, as said waste is in the upper chamber.

When the lower valve is closed, if you keep turning the spindle, theupper valve will open and let the back water into the uppefchamher andout of the waste. Both valves openand shut with the water.

screw-stein provided with wings and with a valve opening with the water,and the lower valve and the two seats, all as and for the purposes setforth.

' GEORGE F. BARD.
